Neuroscientists at Brown University make strides in pinpointing a biological indicator for the advancement of Alzheimer's disease
In a groundbreaking development, researchers at the Carney Institute for Brain Science have identified electrical activity in the brain that could potentially predict the progression to Alzheimer's disease. This research, supported by the National Institutes of Health, including the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative, and funded by a Zimmerman Innovation Award in Brain Science from the Carney Institute, aims to recreate what's going wrong in the brain to generate this identified signal.
Led by postdoctoral researcher David Zhou, the team plans to move into a new phase of research. However, it has been announced that Jones will now take the lead for the next phase. This discovery could revolutionise the early detection of Alzheimer's disease, as it has been found that two and a half years prior to their Alzheimer's disease diagnosis, patients were producing this electrical activity at a lower rate, shorter in duration, and at a weaker power.
The Spectral Events Toolbox, developed by the researchers, could potentially be used by clinicians to diagnose Alzheimer's disease before it progresses. This toolbox, along with the identified electrical activity, represents a more direct method of assessing how neurons respond to the toxicity associated with Alzheimer's disease.
Key collaboration partners involved in further research on the mechanism generating the discovered brain electrical activity include researchers from the Max Planck Institute for Biological Cybernetics in Tübingen who developed novel measurement systems, as well as teams like Jonathan Kipnis' group at Washington University in St. Louis studying neuronal rhythmic waves related to brain waste clearance. These interdisciplinary efforts aim to understand electrical properties and neural activity patterns that could lead to therapeutic targets against Alzheimer's disease.
Spinal fluid and blood biomarkers can identify the presence of toxic beta amyloid plaques and tau tangles in the brain, which are thought to contribute to Alzheimer's disease symptoms. However, this new discovery in brain activity provides a promising alternative for early detection, as it is a direct measure of how the brain responds to these toxic substances.
The research will continue to be conducted at the Carney Institute for Brain Science, with additional funding coming from agencies in Spain. The team also plans to study the mechanisms of beta event generation using computational neural modeling tools, with the ultimate goal of testing therapeutics that might be able to correct the problem and slow down or prevent the progression of Alzheimer's disease. This research holds great promise for the future of Alzheimer's disease diagnosis and treatment.
